A herringbone gear, a specific type of Herringbone Gear double helical equipment,[1] is a particular type of gear that is a laterally (not in person) combination of two helical gears of opposite hands. From the very best, each helical groove of the gear looks like the letter V, and many together type a herringbone pattern (resembling the bones of a fish like a herring). Unlike helical gears, herringbone gears do not produce yet another axial load.
Like helical gears, they have the advantage of transferring power smoothly because a lot more than two teeth will be in mesh at at any time in time. Their benefit over the helical gears is certainly that the side-thrust of one half is well balanced by that of the other half. This implies that herringbone gears can be used in torque gearboxes without requiring a substantial thrust bearing. Due to this, herringbone gears had been an important step in the introduction of the steam turbine to marine propulsion.
Precision herringbone gears are more difficult to manufacture than equivalent spur or helical gears and therefore 
are more costly. They are used in heavy machinery.
With an considerable capacity to manufacture herringbone (or double helical) gears in quantities from large to small, HZPT Co. is definitely well-prepared to meet up your production needs, whatever the application may be. Employed in ratios up to at least one 1.5 diametrical pitch and modules up to 20, we are able to produce herringbone gears measuring up to 60″ in diameter and 18″ in face width. We can also produce little parts, and provide as-needed and just-in-time scheduling systems. Our die forming, warmth treating, machining, and completing services can be found to cover all steps of the apparatus production process, from start to finish.
We feature an comprehensive material selection, including plastics, nylon, phenolic, alloy steels, light weight aluminum, brass, and bronze. Standard industries that we serve include pumps, pulp and paper, machinery, HVAC, and food digesting, as well as many others. From casting to forging and beyond, we use the ideal equipment forming method for your application and production order.
